THE BIG JUNGLE GYM. (x2).
If you place two Big Jungle Gyms back-to-back, you form an 8' long, 4' deep, 6' high structure...
Kind of an iguana townhouse.
You could separate two iguanas safely - they could still see each other - just not bite.
Or just leave out those middle divider panels and have one giant enclosure!
"Very well thought-out designs".
"Great cages. Thank you".
"I gave your name to my vet".
